Specification of Letters Patent.

Patented Nev. e, 1ere.

Application filed September 12, 1918. Serial No. 253,822.

To all whom t may concern.' Y

Be it known that I, W'ILLIAM WILKIE, of

`34 Garthland Drive, Dennistoun, Glasgow,

Scotland, engineer', have invented certain new and useful Improvements in Pressing- Machines, of which the following is aspeciiication.

My invention, which relates to machines for pressing cloth, has for its object the treatment of the various parts of wearing apparel suoli as collars, cuffs, seams, edges and analogous parts, a more eective method of applying pressure to the raisable block under varying degrees to suit the various thicknesses of cloth, and adapting various forms and sizes of blocks necessary in the pressing operation.

The machine is of the type wherein two longitudinal heated blocks are used, one superimposed above the other and the lower one capable of being raised and lowered. According to my present invention, the upper one is not raisaible ybut slidable at will along guide rail and made to sustain pressure at any position alone,` saidrail, while vthe lower block is rendered adjustable for pressing any thickness of material which is interposed between said two blocks. The said lower block is provided with two plungers which are connected thereto from the underside. The lower end of the plungers bears upon the surfaces of a pair of levers now to be referred to. These plungers are elevated or raised by the depression of a foot pedal, pulling down the members of compound levers connected to said pedal; said levers are jointed at nearly right angles and fulcruaned or pivoted at or near their extremities upon a transverse shaft. The free ends or extremities of said levers support the ends of the plungers with a bar, having inclined planes formed thereupon, interposed therebetween, and exert upon them the maximum lever action. It should be explained that the bar is adjustable slidalbly as opposed to known means of adjusting a wedge by a screw device. The foot pedal is capable of being drawn out or extended. A guard or receptacle of trough formation may be used to receive the articles under treatment and keep them from being soiled. v

In order that my invention may be properly understood and readily carried into effect, I have hereunto appended one sheet of drawings, of which- Figure l is an elevation of a machine for pressing cloth and embodying my invention.

Fig. 2 is an end view of the same broken away at its lower end to show the lever arrangement.

Fig. 3 is a horizontal section taken on the line a, b, Fig. l, and

Fig. a is a part plan of one form of one of the blocks, all hereafter more fully rev ferred to and described.

Referring to the drawings, A is the framework, B is the upper block slida'ble horizontally by the handle C along the guide rail D and made to sustain pressure at any position along said guide rail. E is the lower block- -capaible of being raised 'and lowered and on which the articles to be treated are placed and rendered adjustable for pressing any thickness of materiali. F, G, are the two plungers screwed or otherwise secured to the underside of the lower block E. A pair of levers H, l, are fulcrumed on a cross bar L and bear at their front ends under the bar P as at H2 and I2. Links H1, Il have their upper ends pivotally jointed to the rear ends of said levers as at J, K. The lower ends of the links H1 and Il are connected to the pedal N whose rear end bears and is fulcrumed on the transverse bar O. Interposed between the ends of the plungers F and G aforesaid and the extremities H2, I2 of levers H and I, is a bar P. This bar has inclined planes P1, P2 which slide more or less under the ends of the plungers F and G when it is required to adjust the space between upper and lower blocks 'by means of a lever Q which is fulcrumed as at Q2. The outer end of this lever forms a handle R and the inner end thereof is connected pivotally as at Q1 to a link O3. Said link is pivotally connected as at O2 to the bar P.

It will be seen that the depression of the pedal N will depress the lever H1 and raise the free ends H2 and I2 of the levers H and I, and this movement in coaction with the plungers F, G, brings the block E into pressing contiguity with the upper block B. A weight or counterpoise S having a lever S1 connected to the pedal and fulcrumed at S2 to the frame of machine, is employed to raise the pedal immediately after depression. T are hollow guards or receptacles tol keep the articles from the machine or floor. Said guards or receptacles are indicated in dotted lines in Fig. 3 and are arranged on opposite 'sides of that portion of the frame A. 'on

which the block E is mounted. The block shown in Fig. 4 constitutes one of a variety of forms which may be used to meet the pressing requirements. The pedal lincludes a slidable member N1 which enables the pedal to be lengthened or shortened to vary the leverage thereof. Said slidable member passes through a stirrup N which is connected to the lever S1, said member N1 also having on its under side a series of rack teeth T1 any one of which may be engaged with the lower side of the stirrup to secure said member N1 at any desired adjustment.

Claim:

4In a mach-ine or the type set forth, an upper block slidable horizontally and longitudinall-y in relationship to a lower adjustable Copies of this patent may be obtained for ve cents each, by addressing the Commissioner of Patents.

block kadapted to be raised and lowered and exert pressure on the under surface of said upper block, a pair of plungers depending from and connected to the underside of said lower block, a pair of levers fulorumed on a single transverse horizontal bar carried in the framework of the 'machine and acted upon by a foot pedal, a bar interposed between the lower ends of plungers and the free ends of the aforesaid pair of levers having inclined planes formed on the up- -per side and capable of sliding more or less underneath said plungers by lever mechanism, and means to return the pedal to -normal position after depression.

ln testimony whereof l affix my signature in the presence of two witnesses.
